Application filed October 5,1892. fierial No. 447,962. (No model.)

To a whom it may concern:

Be it known that I, WAI'IMAN M. MORGAN, a. citizen of the United States, residing at Kansas City, in the county of Jackson, State of Missouri, have invented certain new and useful Improvements in Suction and Force Apparatus for Pumping Fluids, of which the following is a full,'clear, and exact description, reference being had to the accompanying drawings, forminga part hereof.

My invention relates to an improvementin a suction and force apparatus, for liftingand pumping fluids, and for taking and discharging water through a vessel, or other marine craft, for propelling and steering same; and my'objects are;first; to construct the apparatus in such a manner that a double discharge is attained, thus increasing the amount of flow without increasing the diameter of the cylinder. Second; to so construct the apparatus in two parts, that four threaded spirals operating in combination, may be utilized for lifting and forcing a body of Water or other fluid through a line of pipe for furnishing a water power to a higher elevation, at a point more or less remote. Third; to construct such an apparatus, which may be placed in the hold of a vessel or other marine craft, so as to discharge a continuous volume of water from its stern for propelling said craft,-for equalizing ballasts, and for fioodin g or freeing a vessel or other craft from water. Fourth; to provide and construct such an apparatus, which will. beefticient, simple, and economical. And with these obects in view to invention consists in the,

novel construction and arrangement hereinafter described, and fully illustrated in the accompanying drawings; in which Figure I, represents a front elevation of my invention, which is incased in a cylinder or drum. Fig. II, represents a top plan view of same, with the supply pipe and discharge pipes attached. Fig. III, is a cross sectional view of the cylinder, taken on line 3, 3, of Fig. II, showing its construction. Fig. IV, is

a detail side view of one of the coupling plates, to which the supply or induction pipes are attached. Fig. V, is arear face view of same. Fig. VI, is a front sectional view of the cylinder, showing the threaded spirals in positicn. Fi VII, is a rear sectional view of same, showing the discharge outlet. Fig. VIII, is a sectional plan view, showing the threaded spirals, and the induction and discharge openings. Fig. IX, is a cross section ofihe cylinder and spirals, showing more clearly the construction of said spirals, and the manner in which they mesh with each other. Fig. X, is a sectional detail view of the stuffing-box, for shafts D, D. Fig. XI, is

I a detail view of the dividing partition, which separates the chambers, in which operate the spirals H, H. Fig. XII, represents a sectional end of the spirals, showing a modified form of construction, in which a rubber or leather cushion or strip is provided, and properly secured in the hollow between the threads; said cushions or strips being for the purpose of preventing the spirals from jarring and working loose, should gravel or sand at any time get in the threads.

Referring to the drawings by letters and fig ures, A, represents the cylinder, constructed substantially as shown, of cast iron or other suitable material.

a, represents a series of rods or bolts, which secure said cylinder rigidly between the end plates or cylinder heads 13, B.

0., represents bosses in the dividing partitions B B, in which the shafts D,D, operate; and the object of this partition is to form a positive division between the spirals H, H.

a represents the points of intersection inside the cylinder, formed by the radius of the inner surface of said cylinder, in which the threaded spirals operate, and thus forms a point of division between the upper and lower spirals.

B, B represent a partition, centrally located in the cylinder, and forms a positive division between the spirals H, H. Said partition consists of two parts B, B, and the edges of these two parts at the point B pressed inwardly until they come together forming openings to, as, for the water to enter the drum.

1), b, b, I), represent the stuffing boxes, constructed substantially as shown in Fig. X, and are provided with caps d, which hold the packing in place around the shafts D, D.

(1,0, are plates which are rigidly bolted to .the cylinder walls, and end plates, by means of bolts 0, c, and to these plates are connected the discharge pipes 0 0 through which the waterxor other fluid is discharged into the main pipe Said plates 0, G, are secured to the cylinder walls by bolts and to the end plates 0, by bolts 0. 1

The plates 0', are formed onv the cylinder heads B, B, in such amanner' that cups, or

concave openingsc are formed in same to permit the water to pass out freely, when leaving the threaded spirals H, II.

The shafts D, D, extend entirely through the cylinder partitions and spirals, and carry:

on'each end gear-wheels F, which mesh together, and distrihutethe power equallyto all the spirals.

-15 E, Eflgrepresent belt-wheels or pulleys I structing the threaded spirals II, Hflwhich revolve in the cylinder A. Thethreads h,

' are so constructed as to form a one-sixth twist, and these th reads are designed to mesh with each other. as seen in Fig. IX; the onesurface to one thread, until the next has taken effect. The spirals areconstructed with three or more, rightand leftthreads, as hereinafter described;--after which they are properly se-* cured in the cylinder on shafts D, D, as illustrated, and geared together by their own threads, and assisted by the cogged gears F. Now in order to understand the operation of these spirals, it is necessary to explain that, as they revolve in the directions indicated by arrows in Figs. VI, VII, VIII and IX, that the front half of said spirals, as the threads separate in their revolutions, will create a Vacuum in the cylinder,into which the water or other fluid is drawn,and when the threads have reached a point on the opposite side, Where they mesh together, they force the water or other fluid out of thecylinder, through the discharge openings; thus taking in by suction, and discharging by force, in equal quantities, a continuous volume or stream of fluid. Said spirals are made right and left, and placed in the cylinder in such a manner that a right and left will mesh together. By referring to Fig. VI, it will be seen that aleft spiral 6, meshes with a right spiral 7, said left spiral 6, being placed in the lower left hand corner of said figure and the right spiral 7, placed in the upper left corner; andin the opposite end of the cylinder, a lower left spiral 7', meshes with an upper right spiral 6, as shown.

Referring to Fig. IX,it is readily seen how the'spirals are formed; but to more fully describe the threads h, I have designated the points of two of them by numbers 2, 3, 4, and 5, and it will be seen that the distance between the points designated by Figs. II and sixth twist being requisite togive a bearing.

'III represents one-sixth of the distance of the circumference, and completes one thread.

Then from 2, to-the center of the next thread, designated by Fig.1V, is equal to one-third of the entire circumference, and from .4, to 5,

equals another one-sixth of theentire cir cumference, and completes the second thread;

thus it will be seen that the distance between the end of the thread designated as number 2, tothe opposite end ofthe next thread, designated as number 5, is equal to one-half of the entire circumference. The spirals are placed in the cylinders in the positions seen s5 1 I in Figs. VI, VII, and VIlIyso as to receive thefluids at their outer extremities, through the cups or concave openings 0 c and discharge it atthecenter on the opposite side,- I

or to receive at'their center, and discharge at-their outerextremities, hygiving a reverse lllOlZlOIltO the revolving spirals. The object spirals being keyed rigidly on the shafts, and

having a suction, which is equal to the dis- I charge,obviates the greatestpossibleamount I of friction, by means'of the equal pressure on both sectionsof spirals, and brings the strain on the shaftsl), D, an d' relieves the end plates or cylinder heads 13, B, from pressure and friction.

' The spirals operating in reverse directions,

tities to the discharge pipes; thus equalizing the strain, and making it possible to use a lighter and thinner pipe, than heretofore found necessary.

The threaded spirals are designed to occupy the entire space within the cylinder so that the threads h, operate in close proximity to the wall of the cylinder. The least possible space is left between the ends of said spirals and the end-plates B, and partitions B, B, so that the water or other fluid may not collect around same to such an extent as to impede its discharge.

In constructing the modified form of spiral, shown in Fig. XII; I provide strips 72., of rubber or leather, and secure them in place in the furrows between the threads h,and these serve to form a tight joint betweenthe spirals, and at the same time, provide a means for preventing the apparatus from jarring and jerking, or spreading apart, should sand or fine gravel collect in the threads.

The cylinder or drum A, is made water and airtight, and in the front side, at each end, is cut a V shaped opening, as seen in Fig. I, and on the edge of the end plates B, B, are formed concave openings or inlets c and over these openings are properly secured the plates 0, O, to which the supply or induction pipes 0 C are attached, through which the water is taken into the cylinder; and measured to the discharge pipe G, by means of the spirals H, H, or the water may be taken in through the discharge pipes O, O, and discharges through the induction pipe 9. The pump has a double action on the water .or other fiuid,'i. e., that of suction on the induction side, and force pressure on the discharge.

In the partition B, B are provided cups or concave openings at, a: which permit the fluids tolenter or leave the cylinder with the least possible resistance. The object of constructing the concave inlet in the end plates, is to permit the fluid to leave or enter with the least possible resistance at the point where the threads h, begin to separate.

This apparatus may be placed in the hold of a vessel or other marinecraft, and connected to the engine in a suitable mannerto furnish power for propelling the craft;

This invention is filed as an improvement over my former application on the method of equalizing and distributing liquids, filed A11 gust 3,-1891.

Having thus fully described my invention,

what I new claim, and desire to secure by Let-- ters Patent, is-

1. A suction and force apparatus, constructed substantially as shown; the air and water tight drum or cylinder A, "rigidly secured between the end plates B, B, the concave inlets constructed in said end plates, which facilitates the'ingress of the fluid; the partition B, having concave openings, through which the fluid finds a free outlet,

as shown and described and when forced by the revolving spirals H, H:

substantially asspecified.

2. A suction and force pump, consisting of the cylinder A, having in its middle a circu- 'lar opening, and in each end V-shaped open- "ings; end plates B, B, having cups or concave middle of the cylinder A, over its middle opening and registering with the openings w, w, of the partition B, B; spirals H, H, in one end of the cylinder meshing with each other,

and spirals H, H, in the other end of the cylinder meshing with each other, said spirals rigidly secured on the shafts D, D said? 'pump provided with proper pipes and mechanism for operating the same, substantially for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.
